ABSTRACT:
This invention relates to improved flexible laminates formed from at least one corona treated polyolefin or polyester film bonded to another polymeric or cellulosic film via an aqueous based laminating ink. The improvement in the flexible laminates resides in the aqueous based emulsion used to print and bond the respective films. The aqueous based emulsion is comprised of an acrylic interpolymer prepared by emulsion polymerizing alkyl(meth)acrylates, .alpha.,.beta.-unsaturated olefins, such as styrene and suitably substituted styrenes, and/or .alpha.,.beta.-unsaturated nitrites, such as acrylonitrile, with an amino(meth)acrylate, an amino (meth)acrylate or vinyl amine.
